Error occurred while executing the listener callback for event DataWritten defined for class asyncio.InputStream

Hi,
I am reading data over TCP/IP from hardware device using
t1=tcpclient("xxxx",xxxx)
I am configuring callback function, so that when ever 210 data byes avaible to read function1() execute.
while t1.BytesAvailable == 0
%wait for data
end
configureCallback(t1,"byte",210,@varargin()function1())

function function1()
Bytes_DATAF1=t1.NumBytesAvailable
DATA=read(t1,210);
decode=swapbytes(typecast(uint8(DATAF1(1,7:10)’),’uint32′));
Bytes_DATAF2=t1.NumBytesAvailable
end
codes doing fine but in middle giving following warning.
Warning: Error occurred while executing the listener callback for event DataWritten
